Detailed ways

Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes, and are not intended to limit the protection scope of the present disclosure.

In the description of embodiments of the present disclosure, the term "comprising" and the like should be understood as open-ended inclusion, ie, "including but not limited to". The term "based on" should be understood as "based at least in part on". The terms "one embodiment" or "the embodiment" should be understood to mean "at least one embodiment". The term "some embodiments" should be understood to mean "at least some embodiments." Other explicit and implicit definitions may also be included below.

As mentioned above, in related industries such as construction and real estate, the use of VR technology can provide users with three-dimensional models for displaying information such as the spatial layout, shape, and area of buildings. For example, in the house rental and sales industry, a three-dimensional model of a house to be rented or sold can be presented to a user, so that the user can conduct a panoramic roaming of the house online.

A panoramic tour of a house involves different viewing angles of the house. During the user's panoramic roaming of the house through VR, multiple perspective conversions will be performed. For example, in the current scene of the house presented to the user, if the user clicks a certain position on the display device for presenting the current scene, the perspective presented to the user may jump.

Due to the large number of points that may trigger the viewing angle in the panoramic roaming of the house, it is currently impossible to control the viewing angle conversion during the panoramic roaming. The user may change the viewing angle to a viewing angle that is very far away from the current scene after clicking a certain position of the display device, or the viewing angle cannot be changed because there is no point at this position that can trigger the viewing angle switching, which causes a decrease in user experience.

According to various embodiments of the present disclosure, a scheme for controlling viewing angle conversion is proposed. For example, the electronic device may acquire at least one parameter related to viewing angle conversion. The electronic device may determine, according to the at least one parameter and a position determined in the current scene of the target space, a target field of view area in the current scene, in which there may be a transition point for triggering the viewing angle transition. Depending on the transition point in the target field of view area, it is possible to switch from the current scene presenting the target space to another scene presenting the target space corresponding to the switch point.

According to the implementation of the present disclosure, the viewing angle of the scene in the target space can be controlled to achieve personalized browsing requirements and further improve user experience.

For example, when the electronic device 110 detects the selection of a certain position in the currently presented first scene and determines the target field of view area, the electronic device 110 will present a prompt of possible viewing angle switching, such as whether or not viewing angle switching occurs, And whether the perspective jump will involve a change in the camera's orientation, and so on. In this way, the user can more intuitively understand the trend of the next viewing angle conversion.

At block 240, the electronic device 110 may render a second scene of the target space based on the target transition point associated with the target field of view area.

In some embodiments, the target field of view area determined by electronic device 110 may include multiple transition points. In this case, the electronic device 110 may acquire information associated with the selection of the transition point. In some embodiments, this information may also be input, eg, as a parameter for controlling the viewing angle transition. The information may, for example, indicate to select the transition point closest to the position 401 selected by the user 102 in the first scene 410 , or the transition point farthest from the position 401 selected by the user 102 in the first scene 410 . In other embodiments, the information may also indicate a predetermined distance in the coordinate system of the scene in the target space, for example.

Through the acquired information associated with the selection of the transition point, the electronic device 110 may select a target transition point from a plurality of candidate transition points included in the target field of view area. For example, the electronic device 110 may calculate the respective distances between the plurality of candidate transition points within the target field of view area and the user 102's selected location 401 in the first scene 410 . A target transition point is selected from a plurality of candidate transition points based on a comparison between these distances or based on a comparison between these distances and a given predetermined distance.

As shown in FIG. 4B , after determining the target transition point, the electronic device 110 may transition from the currently presented first scene 410 to the present second scene 420 in the target space.

It is also possible that there is no transition point in the target field of view area determined by the electronic device 110 that can trigger the viewing angle jump, in this case, the electronic device 110 can select the scene image capture with the first scene 401 The associated camera position 403 is adjacent to a transition point.

Optionally or additionally, if there is no transition point capable of triggering a viewing angle jump in the target field of view area determined by the electronic device 110, the electronic device 110 may also present a situation where no candidate transition point exists in the target field of view area. A prompt that prompts or recommends that the user update the parameters used to control the perspective transition.
